Isnora, who was undercover at the time of the shooting, testified in his NYPD trial that he believed Guzman held a firearm in his hand – and that this fear trumped the detective’s reluctance to use his gun.

“I wasn’t going to wait for him to pull up and ‘Boom!’ I wasn’t going to wait for that,” Isnora said, providing his first public statements since the shooting, which claimed Bell’s life on the morning he was to be married.
